\footnotesize{\raggedright{\textit{Notes}: In the column denoting sampling level,``HH" signifies the selection of one person per household and ``Ind.'' indicates that multiple household members were eligible for selection into the survey. In the case of the NLS surveys, it is also possible that several household members were interviewed \textit{across} surveys (e.g., a mother and daughter were interviewed for the NLSMW and NLSYW surveys, respectively). In the third column, ``racial sampling'' refers to the oversampling of Black respondents. Oversampling occurs in 3 ANES cross sections and in 2 GSS cross sections. Weights are only available in five out of seven ANES cross sections. A survey receives a checkmark in the ``childhood region available'' column if it asks respondents where they were born and/or where they grew up with sufficient detail to identify the four Census regions. A survey receives a checkmark in the ``household size available'' column if it includes sufficient information to calculate the number of individuals living in the respondent's household.}}
